GLASS-POLISHING WHEEL.

SPECIFICATION forming* part of Letters Patent N0.. 421,727, datedFebruar); 18, 1890.

Application filed January 1,9, 1887., Serial No. 224,758. (No model.) y

To all whom it may concern:

Beit known that I, WYMAN KIMBLE, of Honesdale,in the countyof Wayne andState of Pennsylvania, have invented a new and Improved Glass -PolishingWheel, of which the following is a full, clear, and exact description.

This invention relates to glass-polishing wheels, the object of theinvention being to provide a wheel that shall be cheap, durable, andeficientin operation, and one wherein a perfectly-true operating-edgemay be produced, as maybe desired; and to the end named the inventionconsists of a wooden polishing-wheel composed of sector-sections, eachof which sections is so cut and connected to the adjacent sections thatthe grain of the wood of each section will run at about right angles tothe forward radial edge of the section, as will be hereinafter morefully described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures ot' reference indicatecorresponding parts in all the views.

Figure l is a side view of a polishing-wheel constructed in accordancewith the terms of my invention. Fig. 2 vis an edge view of the wheelillustrated in Fig. l. Fig. 3 is a side view of a modiiiedconstruct-ion, and Fig. 4 is an edge view of the constructionillustrated in Fig. 3. Y

In constructing such a wheel as the one illustrated in the drawingsabove referred to I provide a number of sector-sections, which, whenunited, will constitute a circular wheel or disk, the sections, whichare shown at l0, being preferably united by dovetail projections, asshown at ll. In forming the sections they are cut so that the grain ofthe wood will run at about right angles to the forward radial edge ofthe section, and in practice I prefer this edge to be the one providedwith the dovetail projection, as is illustrated in Figs. 1 and 2. Froman inspection of Fig. 1, wherein the grain of the wood isy representedby wavy broken lines, it will be seen that the grain of each sectionruns at about right angles to the forward radial edge of the section,the wheel being supposed to revolve in the direction of the arrowshownin connection therewith in Fig. l.

To unite the several sections to form a wheel three sections are firstunited to form oney half of the wheel, and then three more sections toform the other half, when the two halves are united.

By forming the wheel as described I provide for an even wearing of the4wheel. at all points upon its peripheral edge, and at the same time Iprovide for aA proper shaping of the operating-edge of the wheel, for itwill be seen that the sharpening-tool may be held to the peripheral edgeof the disk, and as the disk or wheel is revolved it will always operatewith the grain.

In Figs. 3 and 4 I illustrate a construction wherein thedovetail jointsare dispensed with, and the various sections are united bytongueand-groove connections; but in this construction I have found itadvisable to provide additional uniting devices in the shape ofdouble-pointed tacks, such as those shown at 2.

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patentl. A woodenpolishing-Wheel composed of a series of sector-sections united together,the grain of the wood of each section being at about right angles to theforward radial edge of the section, substantially as described.

2. A wooden polishing-wheel composed of a series of sector-sectionsunit-ed by dovetail joints, the grain of the wood of each section beingat about right angles to the forward radial edge of thesection,lsubstantially asv described.

WYMAN KIMBLE.
